|  | /** | ||
|  |  * Creates a function which is a composition of the passed asynchronous | ||
|  |  * functions. Each function consumes the return value of the function that | ||
|  |  * follows. Composing functions `f()`, `g()`, and `h()` would produce the result | ||
|  |  * of `f(g(h()))`, only this version uses callbacks to obtain the return values. | ||
|  |  * | ||
|  |  * Each function is executed with the `this` binding of the composed function. | ||
